Abstract

The invention discloses a battery pack and a vehicle. Wherein the battery pack includes: a casing; a battery module; a fireproof heat shield; an explosion-proof membrane, the battery module is arranged in the casing and the battery module includes: a bracket and a plurality of cylindrical battery cells , the bracket includes a first bracket and a second bracket, the battery cell is arranged between the first bracket and the second bracket, the fireproof heat shield is arranged on the bracket and corresponds to the For the positive pole of the battery cell, a buffer cavity is formed between the fireproof heat shield and the positive pole of the battery cell, and the explosion-proof film seals the buffer cavity. By adding a fireproof heat shield and an explosion-proof membrane, the heat transfer and spread of the battery cells can be effectively prevented, thereby improving the safety of the battery pack.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a battery pack and a vehicle. Background technique [0002] In extreme cases, the power battery of a traditional new energy vehicle will experience thermal runaway, which will cause the battery cell to burst into flames, and the explosion phenomenon mostly occurs at the positive pole of the battery cell, posing a great hidden danger. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. Therefore, an object of the present invention is to propose a battery pack, the battery cells of the battery pack can effectively prevent the heat transfer and spread of the battery cells when they explode , thereby improving the safety of the battery pack. [0004] A battery pack according to an embodiment of the present invention includes: a housing, a batte...
